Abstract

A system and method for controlling an EMC protection apparatus in a removable component. The removable component is inserted into an end product. As a result of the insertion power is applied to the EMC protection apparatus. A determination is made as to whether a power good signal is detected within the removable component. In response to a power good signal, an EMC protection device is rotated from a retracted state to an engaged state such that the EMC protection device is placed over an enclosure opening in the removable component forming an EMC seal. Full functionality of the removable component can be delayed until such time as the rotation is completed.

First claim

What is claimed is:

1. A method for controlling an EMC protection apparatus in a removable component, comprising:
inserting the removable component into an end product;
applying power to the EMC protection apparatus;
determining the presence of a power good signal at the EMC protection apparatus; and
in response to the power good signal, rotating an EMC protection device on the EMC protection apparatus from a retracted state to an engaged state, wherein the engaged state places the EMC protection device over an enclosure opening in the removable component.

2. The method of claim 1 further comprising:
preventing full functionality of the removable component until completion of the rotating.

3. The method of claim 1 , wherein rotating causes the EMC protection device to wipe against a portion of the enclosure opening.

4. The method of claim 1 further comprising:
disconnecting power from the removable component; and
rotating the EMC protection device from the engaged state to the retracted state.

5. The method of claim 4 further comprising:
in response to disconnecting power, disabling full functionality of the removable component.

6. The method of claim 4 further comprising:
generating an alert that power has been disconnected from the removable component.

7. The method of claim 1 wherein power for the EMC protection apparatus comes directly from the end product.
